Charles and GenevieveEdit
Charles and Genevieve are currently dating. They have a very caring relationship which is seen by some as quite strange (due to doing things such as sharing one scarf when Charles "accidentally" forgot his). It is shown that Genevieve and Boyle have a lot in common- they both have dogs, sleep on the floor, and enjoy weird food that others would find disgusting. The two have decided to have a child together and their adoption papers have gone through.
